System for controlling body implantable action device
First Claim
1. In a system comprising a body implantable device and a sensor assembly for programming or reprogramming said action device, which device is operable to act upon the body in response to changes in a sensed parameter and which has circuitry for deciphering coded signals used to program said device, the improvement comprising said sensor assembly being a separate, independent assembly which is independent of the action device, which is capable of being implanted within a body, and which includes:
- sensor means for sensing a physiological parameter in a body, signal converting circuitry means for converting signals generated by said sensor means to coded electrical signals, such as conventional digital program codes of the type normally used in programming or reprogramming the action device, and transmitting means for transmitting said coded electrical signal related to the sensed parameter to the action device which is operable to decipher the coded electrical signal and act accordingly, upon the body.

Abstract
The system includes a sensor assembly comprising a body implantable physiological sensor for controlling a body implantable action device operable to act upon the body in response to changes in a physiological parameter sensed by the sensor. The body implantable action device can be a heart pacing device, a drug infusion pump, or other device which acts upon a human body. The sensor assembly includes a transmitter for transmitting coded signals to the action device which has programming circuitry for deciphering the signals received from the sensor assembly generated by the sensor which is in a location away from the location of the action device. Once these signals have been deciphered, the programming circuitry can adjust the output from the action device, such as the rate and A-V delay of pacing pulses from the pacing circuitry. In one embodiment, the transmitter is a radio transmitter and the programming code transmitted therefrom is picked up by an output terminal, such as a distal electrode of a pacing lead, which acts as a pickup antenna.
